Introduction
The cosine rule
Applications of geometry and trigonometry
Year 12
This is another in the Further Maths Units 3 and 4 series on Geometry and Measurement (Modules). Having looked at the Sine Rule I now look at the Cosine Rule which allows us to find missing sides and angles of non right-angled triangles where we have two sides and an included angles. There are lots of worked examples showing how to find missing sides and angles and some VCAA worked examples from past papers. All explained in an easy to understand way.
